Now, Google has updated the graphics verification code solution- reCAPTCHA. The reCAPTCHA API has been updated to the V3 version. The biggest feature is the use of distorted text to test real users.
The primary problem solved by reCAPTCHA V3 is to minimize the possibility of deceiving machines, or even not. Therefore, in this version of the solution, Google tries to use various signals to determine the authenticity of the user.
